So, my two cents:
Gachas are, and have always been, a method of creating revenue for the creator. Nothing else. It uses the lure of one or a handful of very 'special' items to get customers to give them money for a chance on getting an item they want. I have always felt gachas are annoying. You go to a sales event, and you see an item you really want, then you look closer, and realize it's a gacha. I don't want acid green panties, or a dog bowl with smiley faces on it in 15 different colors of smiley faces. I want to buy the item I want without having to pay for an astronomically low chance of getting the item I really want.
There have been so many times I have come across an item and just fell in love with it, to the point that I was willing to pay the price for it, even if was expensive, only to see the gacha machine and let out a sigh, and walk away. So, when you look at it that way, you are losing many other definite sales, with zero chance of having an unhappy customer. I was told by one of the biggest sellers of homes in SL, "Your customers are your store. If they are happy, you're happy. Without them, you just have a building with a bunch of stuff in it." Paraphrasing Paigeypoo.
As I said previously, they are a method of revenue for many people from all sides of the equation. I truly do hate that so many people will be taking such a hard blow financially. You can't beat a dead horse to make it run faster, though. The decision has already been made, and there is a better chance of getting the ultra-rare fatpack in a single pull, than changing the decision LL has made. I truly do hope that they will listen to the outcry of so many creators here, and extend the deadline.
I do hope creators find a way to recover the lost revenue, and I really do hope that the creativity that went into some of those gacha items will not be wiped away. I can't say that I will be sad to see the gacha craze disappear, though.
I do also wonder if the 'no copy' element may have played into the decision? Imagine just dropping several thousand L$ to get that one item you wanted, then you rez it in just the wrong spot. Gone. No refunds, no replacements, nothing for the money you just spent for the incredibly small chance to get the item that just vanished without a trace.
Anyways, that's my two cents.
